|Determination of Triethylamine in Air by Flow-injection Chemiluminescence - Ping Yu, Gaifen Guo|
A novel flow-injection chemiluminescence (CL) method for the determination of triethylamine had been established in this study. Based on the chemiluminescence reaction between triethylamine and sodium hypochlorite in alkali condition, the fluorescein has strong sensitization in this chemiluminescence reaction. Under the optimized conditions of chemiluminescence reaction, FI parameters and the absorbing efficiency of triethylamine in the air, the enhanced intensity of chemiluminescence was propor...

|APPARENT PLASMA HYPEROSMOLALITY IN ALCOHOLIC INTOXICATION - FONTAN, M.|
THE TERM APPARENT OSMOLALITY REFERS TO THE MEASURED VALUE EXPRESSED IN MILLIOSMOLS/KG OF WATER DETERMINED BY MEANS OF OSMOMETERS-CRYOSCOPES WHOSE OPERATING PRINCIPLE IS BASED ON THE DECREASE IN THE FREEZING POINT AS A FUNCTION OF THE CONCENTRATION OF MICRO- OR MACRO-MOLECULAR PARTICLES IN THE MEDIUM. THE APPARENT OSMOLALITY OF PLASMA INCREASES PARALLEL TO THE LEVEL OF ALCOHOLEMIA; IT IS NOT ACCOMPANIED BY A PARALLEL DECREASE IN THE MEASURED RESISTIVITY OF THE PLASMA...

|Spatial and temporal variability of soil temperature, moisture and surface soil properties - Hajek, B. F.|
The overall objectives of this research were to: (l) Relate in-situ measured soil-water content and temperature profiles to remotely sensed surface soil-water and temperature conditions; to model simultaneous heat and water movement for spatially and temporally changing soil conditions; (2) Determine the spatial and temporal variability of surface soil properties affecting emissivity, reflectance, and material and energy flux across the soil surface...

|Architecture for time or transform domain decoding of reed-solomon codes - NON|
Two pipeline (255,233) RS decoders, one a time domain decoder and the other a transform domain decoder, use the same first part to develop an errata locator polynomial .tau.(x), and an errata evaluator polynominal A(x). Both the time domain decoder and transform domain decoder have a modified GCD that uses an input multiplexer and an output demultiplexer to reduce the number of GCD cells required. The time domain decoder uses a Chien search and polynomial evaluator on the GCD outputs .tau.(x) an...

|A Study of the Stellar Population in Selected SO Galaxies - Perez, M.|
The goal of this program was to observe at least two SO galaxies with abnormal colors in the blue and clear optical signatures of dust and gas. The galaxies NGC 2217 and NGC 1808 were observed at least in one of the IUE cameras (1200-200 and 2000-3200 A) during the 13th episode, using the 4 US1 shifts assigned to this program. The galaxy NGC 2217 had been found to be part of a subgroup of SO galaxies with external gas rotating in retrograde motion with respect to the stars...

|The shuttle glow: A program to study the ram-induced phenomena - Anderson, H. R|
In January 1984, a proposal was submitted to NASA Headquarters entitled The Shuttle Glow: A Program to Determine the Physics of the Ram induced Phenomena. This proposal included the following elements in a shuttlebased experiment: (1) The use of a special flat generating surface 1 x 3 m on which the glow can be produced and observed. This surface will be maneuvered to vary the orientation of ram flow and of projected component of geomagnetic field...

|The control data ''GIRAFFE'' system for interactive graphic finite element analysis - Park, S.|
The Graphical Interface for Finite Elements (GIRAFFE) general purpose interactive graphics application package was described. This system may be used as a pre/post processor for structural analysis computer programs. It facilitates the operations of creating, editing, or reviewing all the structural input/output data on a graphics terminal in a time-sharing mode of operation. An application program for a simple three-dimensional plate problem was illustrated.

|Floating Potential Probe Langmuir Probe Data Reduction Results - Morton, Thomas L.|
During its first five months of operations, the Langmuir Probe on the Floating Potential Probe (FPP) obtained data on ionospheric electron densities and temperatures in the ISS orbit. In this paper, the algorithms for data reduction are presented, and comparisons are made of FPP data with ground-based ionosonde and Incoherent Scattering Radar (ISR) results. Implications for ISS operations are detailed, and the need for a permanent FPP on ISS is examined.

|National Space Transportation Systems Program mission report - Collins, M. A., Jr.|
The 515-41B National Space Transportation Systems Program Mission Report contains a summary of the major activities and accomplishments of the sixth operational Shuttle flight and fourth flight of the OV-099 vehicle, Challenger. Since this flight was the first to land at Kennedy Space Center, the vehicle was towed directly to the OPF (Orbiter Processing Facility) where preparations for flight STS-41C, scheduled for early April 1984, began immediately...

|Analysis of Particle Image Velocimetry (PIV) Data for Application to Subsonic Jet Noise Studies - Blackshire, James L|
Global velocimetry measurements were taken using Particle Image Velocimetry (PIV) in the subsonic flow exiting a 1 inch circular nozzle in an attempt to better understand the turbulence characteristics of its shear layer region. This report presents the results of the PIV analysis and data reduction portions of the test and details the processing that was done. Custom data analysis and data validation algorithms were developed and applied to a data ensemble consisting of over 750 PIV 70 mm photo...

|Improved Modeling of Finite-Rate Turbulent Combustion Processes in Research Combustors - VanOverbeke, Thomas J|
The objective of this thesis is to further develop and test a stochastic model of turbulent combustion in recirculating flows. There is a requirement to increase the accuracy of multi-dimensional combustion predictions. As turbulence affects reaction rates, this interaction must be more accurately evaluated. In this work a more physically correct way of handling the interaction of turbulence on combustion is further developed and tested...

|Space Radiation Effects on Graphite-Epoxy Composite Materials - Milkovich, S. M.|
Radiation effects on engineering properties, dimensional stability, and chemistry on state of the art composite systems were characterized. T300/934 graphite-epoxy composite was subjected to 1.0 MeV electron radiation for a total dose of 1.0 x 10(10) rads at a rate of 5.0 x 10(7) rads/hour. This simulates a worst case exposure equivalent to 30 years in space. Mechanical testing was performed on he 4-ply unidirectional laminates over the temperature range of -250 F (116K) to 250 F (394K)...
